77. OVERHAUL. To disassemble
rear transmission housing, procet^d as
follows: Remove differential lock ac-
tuator shaft and shift fork. Remove snap
ring from rear of countershaft (3-Fig.
106), then tap shaft forward from hous-
ing and remove gear (4) and bearings.
Insert a brass rod between ring gear and
bevel pinion gear to prevent shaft from
turning, then remove nut (7) from bevel
pinion shaft (15). Remove differential
carrier bearing cases and withdraw dif-
ferential assembly. Loosen set screw
securing range shift rail (20-Fig. 98),
remove snap pin (26) and pull rail for-
ward out of housing and withdraw fork
(21). Remove shift lever (28) and arm
(24). Remove cap screws securing bevel
pinion bearing case (10-Fig. 106). Tap
bevel pinion shaft rearward out of hous-
ing, then remove front bearing case and
bearing. Be sure to retain shims (11) for
use in reassembly. Remove snap ring
(13) and press shaft out of bearings (14).
To remove pto output shaft (26), remove
front bearing (17) using a suitable puller.
Remove bearing case (28) mounting cap

Bevel pinion shaft (15) is available only
as a matched set with bevel ring gear. If
renewing shaft or bearings, backlash
and gear mesh must be checked and ad-

TRANSMISSION
(Models L235-
L275-L355)
78. On all models, a four-speed main
transmission unit is coupled with high-
low range transmission to provide eight
forward speeds. Models L235 and L275,
a mechanical shuttle (forward-reverse)
section allows forward operation in any
of the eight speeds and reverse opera-
tion in first seven speeds. Eighth speed
is locked out in reverse for safety
reasons.
On Model L355, a hydraulically actuated
forward-reverse shuttle transmission
allows forward or reverse operation in
any of the eight speeds.
